Use when writing or reviewing code that handles external input, manages access, touches data or crypto, or changes dependencies. Triggers: endpoints, auth/authz, DB/ORM, file handling, secrets, "is this secure?", "security review". NOT for formatting, pure UI, or explaining code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Securing Code ## When to Use - Implementing any feature, endpoint, service, or component - Writing auth, session management, or access control logic - Handling file uploads, secrets, crypto, or sensitive data - Reviewing code changes for security issues - Checking a diff, branch, or PR for security correctness ## When Not to Use - General code review without a security focus — `code-review` invokes this skill internally for its security lens - Explaining code without modifying it - Formatting or linting only - Writing documentation unrelated to security controls ## Invocation Notice - Tell the user when this skill is running: `securing-code`. Skip the notice when the user asked for the skill by name or slash command; spelling and spacing need not match. A phrase from this skill's own trigger list is not a name — naming the work is not naming the skill. --- ## Tier 1 — Core Principles (Apply to Every Task) These apply regardless of task type — implementation or review. ### Secure Design Principles - **Assume breach** — design as if the system will be compromised; no single point of trust …

How to install
mdr add ahgraber/skills/securing-code@sha256:a30b70ec7e559a9bThe line at the top of this page pins the label git:20260819.209d97b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
